There are three systems on your golf cart that have to work in conjunction to make things run. They are fuel, fire, and compression. If one of them is not present, the coach can not fire up. Each of the three has several components or players that help get their job done. You have parts like the Club Car Ignition Coil and the ignitor working in unison to produce a spark at the plug on the fire end of things. If they are not in sync, your timing will be off. That's just fancy tech talk meaning the spark happens at the wrong time. This could cause anything from the occasional backfire to making the golf cart a 900 pound paperweight.Getting the spark good and hot is the job of the golf cart ignition coil. These aftermarket replacement units do an excellent job of making that happen. This product will work for the 1984-1989 Club Car DS models.
